专利类型发明专利
摘要【中文】一种高粘高弹的超薄磨耗层,其材料组成包括粗集料61%‑70%、细集料23%‑32%、高粘沥青5.5%‑7.5%、温拌添加剂0.15%‑0.3%和木质素纤维0.2%‑0.5%。所述的高粘沥青是以70#石油沥青为基质沥青,内掺16%和18%的SINOTPS改性而得到。本发明掺入一定掺量的改性剂形成高粘沥青超薄磨耗层,增加了路面的稳定性和耐久性,提高了沥青超薄磨耗层的路用性能,可应用在新建路面表面层和旧路功能性罩面层。 【EN】The material composition of the ultra-thin wearing layer with high viscosity and high elasticity comprises 61-70% of coarse aggregate, 23-32% of fine aggregate, 5.5-7.5% of high viscosity asphalt, 0.15-0.3% of warm-mixing additive and 0.2-0.5% of lignin fiber. The high-viscosity asphalt is obtained by taking 70# petroleum asphalt as base asphalt and internally mixing 16% and 18% of SINOTPS for modification. The invention is mixed with a certain amount of modifier to form a high-viscosity asphalt ultrathin wearing layer, thereby increasing the stability and durability of the pavement, improving the pavement performance of the asphalt ultrathin wearing layer and being applied to the surface layer of a newly-built pavement and the functional finish coat of an old pavement.
